Default Moth the T-Rex

Nothing radical, I'm thinking about 2-4 inch shorter tail boom and main blades. Can it be done? Has anyone tried to make their T-Rex a little closer to a 300 size?

The original 450X had a shorter boom and only ran 315mm blades.

The problem is, as you reduce the blade length, you significantly decrease the rotor disk size, which increases the disk loading as you don't loose much weight by shortening the boom adn blades.

I've actually thought about doing the opposite for the endurance competition, and maybe a scale application. A stretch Rex. With longer blades, maybe flat bottom, and extended tail boom.
